What can an infection in the root canal of a tooth cause?

ANSWER

In addition to an abscess, an infection in the root canal of a tooth can cause:

1. Swelling that may spread to other areas of the face, neck, or head

2. Bone loss around the tip of the root

3. Drainage problems extending outward from the root. A hole can occur through the side of the tooth, with drainage into the gums or through the cheek into the skin.
